iphone - iOS: After one animation, all other views start animating -

-

i have peculiar problem. in ios app i've developed, after running animations below find various other elements of ui animate whenever appear.

for instance, once these animations below run, every time navigate new tab in app, ui elements animate top left corner of iphone proper positions. have specified no animations these ui elements in other tabs , in fact elements have no access to, activity indicator in iphone status bar, begin animate on own.

what going on? why occur after animation below executed? before running animation (with button press) other ui elements in other app tabs not animate @ when appear, expected behaviour.

- (ibaction) btnchosenpostcodeclicked:(id)sender {    //prep animations   startview.alpha = 1.0;   postcodeview.alpha = 0.0;    [self.view addsubview:postcodeview];    [uiview beginanimations:@"chosenpostcodeanimation01" context:nil];    [uiview setanimationduration:animationspeed];   [uiview setanimationtransition:uiviewanimationtransitionnone forview:self.view cache:yes];   [uiview setanimationdelegate:self];    [uiview setanimationdidstopselector:@selector(chosenpostcodefadeoutanimationdone:finished:context:)];    startview.alpha = 0.0;    [uiview commitanimations];  }  - (void)chosenpostcodefadeoutanimationdone:(nsstring *)animationid finished:(nsnumber *)finished context:(void *)context {     //prep animations     postcodeview.alpha = 0.0;      [uiview beginanimations:@"chosenpostcodeanimation02" context:nil];      [uiview setanimationduration:animationspeed];     [uiview setanimationtransition:uiviewanimationtransitionnone forview:self.view cache:yes];      cgrect newrect = cgrectmake(42, 157, 239, 180);     imvbubble.frame = newrect;      postcodeview.alpha = 1.0;  }

you're missing 

[uiview commitanimations];

in chosenpostcodefadeoutanimationdone absolutely becoming part of animation!

c# - Is it possible to remove an existing registration from Autofac container builder? -

-
something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
